Help cyanide vs SN comparison

[kosameAmagai]

if we are comparing cyanide, more especifically potassium cyanide (KCN), against SN in terms of reliability, time it takes until unconsciousness/death and peacefulness which one is better in each aspect? considering we are doing the full SN protocol ( anti emetics, beta blockers, benzos, etc)? thanks

A very small amount of the proper form of cyanide is extremely lethal, and is also extremely hard to get in most places. The PPH has more.
